Which kind of weather usually forms over the northwest united states in the summer because of maritime polar air masses? 1 )fog 2)dry heat 3) heavy snow 4) heavy rain

1 )foggy.

Explanation:

As air mass is a large body of air that remains stable over the area for a larger period like days or weeks it produces heat exchange on land and as well on waters.  As maritime polar air masses (M.P) are cool and moist hence they bring cloudy and damp weather to the USA covering the northern Atlantic and Northern Pacific oceans, mostly influenced by the pacific northwest and northeast air masses. They can form any time of the year and are not as cold as the continental polar air masses.

As someone who lives in the northeast, we get a lot of fog in the summer.

snow - we don’t get in summer

rain - we’ve recently been getting a lot of rain but i think it’s because of global warming, but either than that it’s mainly in the spring of april.

dry heat - we mainly have humid heat vs. dry heat

so that leaves us with fog.

vote brainliest if this helped! :)

The mass has escaped into a gas which you can not see so the law stays true.
